and its composition determined; ! and the calamine of 
Malham has been chemically examined, and found to contain

The lists of Zoological donations exhibit an increase 
beyond any former year in the number of Birds, a large 
proportion of which were procured in North America by 
the same donor, 3 whose travels have enriched so many other 
parts of the Museum. Some valuable additions have been 
made to the foreign Insects, whilst there have been so many 
accessions to the catalogue of native Shells, as leaves room 
to hope that before long an instructive arrangement of the 
British mollusca may be accomplished. 
Such an arrangement of the Botanical collections has 
been commenced, by incorporating together the extensive 
herbariums presented in 1827, classifying them according to 
the most improved modification of the natural system 
adopted in the great work of De Candolle, and accompanying 
the specimens with illustrative remarks. The Curator 4 has 
presented a fasciculus containing the first order complete, 
as a specimen of the method which he has pursued. Among 
the donations to this department in the last year, is an 
extensive series of North American plants : 5 a foundation 
has also been laid, by a present of rare seeds and nuts 6 , for 
1 , 2 By the President of the Society.
